Customers are saying

Customers are pleased with the 450VA Battery Back-Up System's long battery life, strong performance, compact size, and affordable price. Many appreciate its surge protection and ease of use, finding it simple to set up and operate. While some users wish for a USB port and find the unit's weight or alarm to be a minor drawback, the overall feedback is positive. The number of outlets is also frequently praised as sufficient.

    I purchased this to power my ONT whenever we have power outages and it's perfect for what i bought it for. I only have the Optical Network Terminal plugged into it and it powers it for well over qan hour with no issue. It's quite small and is easy to hide as well.

    I bought this to keep my internet and WiFi running with all these unannounced power outages, It kept everything running for 12 hours. It is a very compact unit that fits inside my wiring enclosure.

    PART OF MY TOTAL POWER BACKUP SYSTEM

    Purchased this to bridge the gap when I have a power outage. My gas backup generator kicks in to power the house 15 seconds after a detected power outage. In the meantime, my computer will go offline without this unit. With the unit, my system stays up until my house generator kicks in so I have uninterupted power for my computer system. I also bought one for my modem and router to keep those online during the cutover in a power outage. This keeps my security cameras and video doorbell operating without interuption. There is a separate bank of surge protected outlets that I use for non-essential electronic accessories.

    I have not needed the back up power yet. It is better to have and not need. Than to need and not have. Unit is compact and easy to use when needed.

    I really like this UPS. Good price for the security of not loosing power. It has a good number of plug-ins and it’s not too large it fit by my computer. I can fit all my components in this unit and it still has a few extra plugins.

    This device really helps you if you have a nas or anything that needs to be charged so I recommend getting this it's not at a very bad price and you have surge protection for both signs and the battery backup again to charge anything you need at that moment if the power went out

    So far so good. Been using for a month now. One power spike has occurred, but seems the device caught it as I didn't notice any flickering with the devices plugged in. If any power outage happens, I'll update my review to reflect my thoughts. So far very happy with the peace of mind knowing my Devices are well protected.

    Great battery backup. Easy to use and very needed since we have a lot of temporary power outages. My computers were suffering from turning off in the middle of work when the power goes out for a minute or two.

    Works great not only for computers and other computer-related items, But also as a Backup for Lift Chairs for Elderly during a power outage My mother was stuck in her lift chair for more than an hour and had to use the restroom couldn't get up until the power came back on after the storm had passed, we talked on the phone for a bit and I got an idea to buy it for her chair so at least she could get out of it during a power outage... Maybe you could have a new market for it selling it as lift chair battery back up... She loves it and has used it twice when the power has gone out during other storms so far she has a lamp plugged into as well so she can see where she's going once she gets out of the chair...
